Road to 90 buff

Hi all, I am currently on the road to 80 buff on Dynamis, the 90 days for which won't be up until about a month after the launch of Dawntrail. I was curious as to when the new "road" buff is typically introduced and if my existing buff will go away or if it will be automatically upgraded to the new buff.

I do not know the answer, but based on the way similar things tend to work in game i have a guess. My guess is that your buff would remain as it is. Same benefits, same levels, same expiration.
